ABSTRACT

A CAMERA ADAPTED TO RECEIVE A FLIM CARTRIDGE CONTAINING ROLL FLIM PERFORATED AT PREDETERMINED METERING INTERVAL INCLUDES A FILM ADVANCING MECHANISM WHICH IS LOCKED AGAINST FURTHER FILM TRANSPORT WHEN A FRESH FRAME IS AN REGISTRY WITH THE CAMERA&#39;&#39;S EXPOSURE AREA. A SHUTTER RELEASE LEVER IS OPERABLE TO EFFECT EXPOSURE OF THE FLIM, AND A DOUBLE EXPOSURE PREVENTION MECHANISM PREVENTS DEPRESSION OF THE SHUTTER RELEASE LEVER PRIOR TO TRANSPORT OF ANOTHER FRAME TO THE CAMERA EXPOSURE AREA UPON COMPLETION OF AN EXPOSURE. THE DOUBLE EXPOSURE PREVENTION MECHANISM IS AUTOMATICALLY DISABLED WHENEVER A CARTRIDGE IS NOT LOCATED IN THE CAMERA. A SENSING LEVER 54 ABUTS A SURFACE ON THE CARTRIDGE RECEIVED IN THE CAMERA. IF NO CARTRIDGE IS PRESENT, THE SENSING LEVER IS ROTATED BY SPRING 62 TO DISABLE THE DOUBLE EXPOSURE MECHANISM.
